Which of these wines are still good?

I am cleaning out my wines and have some that I'm not sure are still good. If they're servable, I'll serve them at Thanksgiving; otherwise, I'll toss them.

What is the likelhood that each of the following are drinkable?

1. Kendall Jackson, Cabernet Sauvignon, 2001 Collage

1. Kendall Jackson, Pinot Noir, 2000 Vintner's Reserve

2. Indigo Hills, Pinot Noir, 1998

1. Walnut Crest Merlot, 2001

2. Robert Mondavi, Pinot Noir, 1999
